Case 3

Utilitarian LED lighting. Lighting of streets and highways of any category, lighting of bridges and railway platforms

Problem

The modern market offers countless street lamps. The price range is also very wide. However, the strong problem remains related to price/quality ratio: light-technical parameters, reliability, service life - important parameters that many manufacturers simply do not pay attention to:

Aggressive external environment: rain, dust, soot, exhaust gases, particles of oil, antifreeze, unburned fuel.
Result: premature failure of electronic components, reduction in the efficiency of the optics, destruction of internal elements of the luminaire (even appearance of the phase voltage on the housing).

Blinding of drivers
Exceeding the threshold brightness --- >> Temporary blindness of the driver --- >> extremely dangerous situation on the road.
The absence of a blend, a simple form of the housing leads to the direct illumination of the driver's eyes above the threshold brightness.

Vibration and wind affect over the lamps functioning
Vibration effects from vehicles and other external factors.
Strong wind creates a variable load on the lamp and decrease in the stability of its fixation.

Solution - «Four light»

from Team Cave Lighting CL GmbH & Co.KG

Feature «Four light»

Double thickness aluminum alloy housing or oxide coated.

All contacts between different metals pass only through insulating spacers.

Soft mount a protective polycarbonate glass with a relief valve.

Optics is not used. The use of high-quality reflectors.

Electronic circuit boards are covered with a special varnish.

Compliance with IP65.

Full compliance with the claimed IDC.

The choice between 4 IDC types for each particular object.

The special shape of the floodlight and reflectors for an optimal uniform light flux.

Threshold increment of brightness is set to 8%, which means there is no blindness (at demand of ≤15%).

High efficiency

Energy efficiency
We use LEDs from the leading manufacturer CREE are used, the series XML with light flux 160 lm/W and color temperature 3000 to 6000 K.
